ACQUISITION System
Acquiring Signal
System
When you acquire a signal, the oscilloscope converts it into a digital
form and displays a waveform. The acquisition mode defines how the
signal is digitized and the time base setting affects the time span and
level of detail for the acquisition.
Press the “ACQUIRE” button.

Sampling
Use for sampling and accurately display
most of the waveform.
Peak
Detect
Detect the noise and decrease the
possibility of aliasing.

Use to reduce random or uncorrelated
noise in the signal display.

Real time
Set the Sampling mode to Equ time.
The equivalent time sampling mode can
achieve up to 20 ps of horizontal
resolution (equivalent to 50 GSa/s). This
mode is good for observing repetitive
waveforms.
Set the Sampling mode to Real time.
In “Real time” mode, turn the “S/div” knob
to display the real time sampling rate at
corresponding time base scale; In “Equ
time” mode, turn the “S/div” knob to
display the equ time sampling rate at
corresponding time base scale”.
